The Turkish president has now cried out islamophobia as generations of Turkish immigrants have refused to assimilate and the Dutch want to do something about it. Turkey has the advantage in this negotiation due to the refugee crisis. With the European Union refusing to close the borders and remove the hostile invaders Turkey can use its large refugee population as a bargaining chip. This results in a lose-lose situation for Europe, if estranged Turkey can just allow millions of hostile people to flood into Europe, but if Turkey is admitted to the European Union then the refugees get into the EU system and will have freedom of movement within the Schengen zone.
Turkey is playing hardball by outright calling the Dutch Nazis in an attempt to force social pressure because the refugees are not wanted in Turkey either. I would expect genocidal conditions or mass deportations in Turkey should the EU decided to seal its borders and cut Turkey off due to its belligerence. Very unlikely due to the EU’s far left ideological position, but there are nationalist parties in Europe that can effectively force the same conditions if enough European countries are taken over by their movement.
